Hello, I'm new to this forum but was looking for advice on growing the Lithops plant I recently bought. there is a large thread on Lithops but sooo many comments, and haven't seen any (admittedly on a very quick look) that answer my specific questions.
1. It's in a very small pot and the roots are visible at the bottom. Is it a good idea to repot now? (UK climate)
2. If OK to repot, I would like to put several in a bowl. What succulents go well with Lithops and require similar or the same growing conditions? I was thinking about Fenestraria or Pleisopilos, but the former seems to need more water and I wonder if the latter may be too large compared to Lithops.
3. Having seen some of the advice on growing medium, would a mix of coarse sand, aquarium gravel (coarse small pebbles and finer gravel) and a small amount of compost be OK? I have these to hand and don't want to buy expensive cactus compost if not necessary.
4. I have never grown any of these before, (though used to have cacti that thrived on neglect but didn't easily flower). The brightest (east facing) windowsill available tends to get a lot of condensation in frosty weather, so not sure of the best place.
